DISK CONCENTRATION TABLE Russian patent published in 2012 - IPC B03B5/74 B03B5/04 

FIELD: process engineering.

SUBSTANCE: invention relates to dressing of minerals and may be used for separation of different-density fine mineral particles. Proposed concentration table has movable round deck with circular fluting divided into two or more sectors, distributing bin, high-frequency step motor to drive said deck about vertical axis, and separation products collectors. Deck sectors have at least two separation product discharge zones with gradual increased in radii. First least radius zone serves to discharge the product with low specific density. Every other zone with increasing radius serves to discharge the products with increasing density. Aforesaid distribution bin has dovetail-shaped sectors and automatic valve to control initial feed and flush water flow rate at feed brush pipes.

EFFECT: higher efficiency, simplified design.
